A report in the Astronomical Journal last Thursday generated huge excitement among space enthusiasts claiming we have 2 TRILLION galaxies in our Universe based on 3D modeling of images collected over 20 years by the Hubble Space Telescope. This ten-fold increase in galaxies stunned many astronomers who have speculated on how many galaxies exist at least since US astronomer Edwin Hubble showed in 1924 that Andromeda, a neighboring galaxy, was not part of our own Milky Way. A decade earlier, the Rhodes Scholar Hubble returned to graduate school to pursue his passion for astronomy but overcame a posting in France during World War 1 and took up a position at the newly opened Wilson Observatory in Pasadena, CA to pursue cosmology studies. The University of Oregon lays it out for the uninitiated:
Cosmology is the study of the Universe and its components, how it formed, how its has evolved and what is its future. Modern cosmology grew from ideas before recorded history. Ancient man asked questions such as “What’s going on around me?” which then developed into “How does the Universe work?”, the key question that cosmology asks. To religious studies, cosmology is about a theistically created world ruled by supernatural forces. Many of the earliest recorded scientific observations were about cosmology, and pursue of understanding has continued for over 5000 years. Cosmology has exploded in the last 20 years with radically new information about the structure, origin and evolution of the Universe obtained through recent technological advances in telescopes and space observatories.
The Hubble Deep Field images provided data the team confirmed date more than 13 billion years into the past. In fact, it appears that there were a factor of 10 more galaxies per unit volume when the Universe was only a few billion years old compared with today. A significant evolution has taken place throughout the Universe’s history during which galaxies merged together, dramatically reducing their total number. “This gives us a verification of the so-called top-down formation of structure in the Universe,” explains team leader Christopher Conselice from the University of Nottingham, UK. The decreasing number of galaxies as time progresses also contributes to the solution of Olbers’ paradox — why the sky is dark at night since so many galaxies are un-observable.

Top-Down Cosmology got a boost almost a decade ago when Cambridge’s Professor Stephen Hawking deduced, as the Telegraph sought to explain, “the early universe can be described by a mathematical object called a wave function and, in a similar way to the light particle, that this means that there was no unique origin to the cosmos: instead the wave function of the universe embraced a multitude of means to develop. ” Here are his prolific writings, including recent thinking on black holes.
In March, some NASA scientists discovered “Super Spiral Galaxies” explaining that,”we have found a previously unrecognized class of spiral galaxies that are as luminous and massive as the biggest, brightest galaxies we know of,” said Patrick Ogle, an astrophysicist at the Infrared Processing and Analysis Center (IPAC) at the California Institute of Technology. Super spirals can shine with anywhere from eight to 14 times the brightness of the Milky Way and possess as much as 10 times our galaxy’s mass. The Caltech NED database is here.
